Introduction – Voltage Level Translation with the LSF Family

Hello, and welcome to The Logic Minute. This video is the introduction to a series of videos on the LSF family of bi-directional multi-voltage level translators. To the right, you can see an example of a typical application circuit in which a single LSF device enables bidirectional communication between two external devices operating at different voltage nodes.
Throughout this video series, you will learn how the LSF translators work from the ground up. The next video in the series explains the bias circuit required to make the device operate. After that, we have a video explaining the proper usage of the enable pin.
And translation is broken up into three videos-- the basics common to all translation applications, how LSF devices achieve down translation, and how they achieve up translation. There are also videos on advanced topics like using a single LSF device to translate from and to multiple voltages simultaneously and biasing the LSF a single supply.
There are currently five functions in the LSF family, and each part number will quickly tell you its features. The last two digits indicate the number of channels that it contains. There are 1, 2, 4, and 8 channel LSF translators available.
The first two numbers indicate the technology family. The LSF01 devices were the first to be released, and the LSF02 are the most recent additions to the family. Please click on the links below to jump to the video of interest, and thank you for watching.
